Abstract

The wavelet method was introduced into overall hull surface fitting from a large number of data points by using twodimensional wavelet transform, and the wavelet coefficients were filtered to obtain a highly compressed wavelet reconstruction hull surface expression. The accuracy of the reconstruction hull surface can be controlled by the value of wavelet coefficients filtering threshold. Finally, an example of a square tail boat with sharp angular change illustrate the validity and reasonableness of this method.
